To all whom it may concern: On the shaft D is a gear-wheel F, and on Be it known that I, ELLWOOD O. LINDSAY, the axle D is a gear-wheel F, one meshing a citizen of the United States, residing in with the other, so that both shafts will turn Philadelphia, Pennsylvania, have invented in unison and preferably at the same speed, 5 certain Improvements in Electric Locomoalthough when it is desired to increase or ditives, of which the following is a specificaminish the speed of the axle the diameter of tion. the gear F maybe varied as required. Mount- The object of my invention is to so coned on the shaft D is the frame G of the mostruct an electric locomotive used especially tor H, having bearings for the armature-shaft 10 on narrow-gage tracks that a large and powh. On the armature-shaft is a gear-pinion erful electric motor can be mounted on the f, which meshes with the gear-wheel F on the locomotive and geared to the driving mechshaft D, so that the motor drives the axle anism. Heretofore in locomotives of this through the pinionfand gears F F. type especially used on narrow-gage railway- It will be seen by referring to Fig. 2 that I5 tracks, such as those around the yards of facthe motor can be of any width desired, the tories and mills, the motor was mounted dilimit being the width of the frames A A of rectly on the axle of the locomotive and bethe locomotive, the motor extending over one tween the wheels, and consequently the size of the wheels. and power of the motor was limited; but by my As shown in the figures, one end of each mo.- 2o invention I can materially increase both the toris supported by bearings of the well-known size and the power of the locomotive and yet form, which rest upon the auxiliary shaft D, use a locomotive having a very narrow gage. while the other end of each motor has a lug In the accompanying drawings, Figure lis h for the attachment of any of the wella side View of a'locomotive, partly in secknown forms of motor-suspension known to 25 tion, illustrating my invention.

The combination of a frame having bearthe bearings, while said bearings necessarily ings, an axle mounted in said bearings havalways remain in the same position in respect ing traction-wheels and a gear-wheel, an into each other. Springs 0 are placed between termediate shaft also mounted in bearings in 1o 50 the frame and the bearings, so that said frame the frame and having a gear-wheel meshing may be yieldingly supported. with the gear on the axle, a motor hung to said intermediate shaft and provided with a gear-wheel meshing with said gear-wheel on the intermediate shaft, substantially as de scribed.

2. The combination of a frame, an axle, bearings therefor mounted in the frame, traction-Wheels on the axle, an intermediate shaft above the axle, bearings for said shaft arigid connection between the intermediate shaftbearings and the axle-bearings, the Whole being free to move independentlyof the frame, a motor-frame mounted on said shaft and provided with an armature-shaft, said armature-shaft being geared to the intermediate shaft, substantially as described.

3. The combination of a frame of an electric locomotive having pedestals, axle-bear ings in said pedestals, springs between the axle-bearings and the frame, an axle mounted in said bearings and having traction-wheels, an intermediate shaft mounted above the axle, bearings for said intermediate shaft, said intermediate shaft-bearings being supported by the axle-bearings so that they will move therewith, a motor-frame hung to the intermediate shaft and extending over one of the traction-wheels, said motor being geared to the intermediate shaft which is in turn geared to the axle, substantially as described.

4. The combination of the frame of an electric locomotive having pedestals, axle-bearings in the pedestals, springs between the axle-bearings and the frame, an axle mounted in the bearings, traction-wheels on the axle, a gear-wheel also on the axle, an intermediate shaft above the axle mounted in bearings arranged in pedestals on the frame of the locomotive, a bar by which the intermediate shaft-bearings are supported by the axlebearings, a motor-frame hung to the intermediate shaft and extending over one of the traction-wheels, a pinion on the armatureshaft of the motor, a gear-wheel on the intermediate shaft With which the pinion meshes and which also meshes with the gear-wheel on the axle, substantially as described.

5. The combination in an electric locomotive, of a frame, pedestals, axle-bearings in said pedestals, an axle mounted in said bearings and having traction-wheels, the frame of the locomotive being increased in Width above traction-wheels on the axles, an intermediate shaft mounted above each axle and geared thereto, bearings for the intermediate shaft supported by the axlebearings, and a motor hung to the intermediate shaft and geared thereto, substantially as described.

'7. The combination of a frame, an axle, bearings therefor mounted in the frame, traction-wheels-on the axle, an intermediate shaft above the axle, bearings for said shaft, a rigid connection between the intermediate shaft bearings and the axle-bearings, the whole be ing free to move independently of the frame, a motor-frame mounted on said shaft and provided with an armature-shaft, said armatureshaft being geared to the intermediate shaft, there being a spring between said rigidly-connected bearings and the frame, substantially as described.

8. The combination in an electric locomotive, of a frame having pedestals, axle-bearings in the said pedestals, axles mounted in each pair of bearings, traction-wheels on the axles and an intermediate shaft mounted above each axle and geared thereto, bearings for the intermediate shaft rigidly connected to the axle-bearings, a spring between the frame and bearing upon said rigidly-connected members and a motor hung to the intermediate shaft and geared thereto, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ELLWOOD C. LINDSAY.
